Welcome to Acid and Bases test. 30 seconds . An Introduction to Chemistry ThoughtCo. Figure 2: Titration Demonstration, The picture was taken during a vinegar titration lab. Most indicators are weak acids, so protons shift from acid to conjugate base. And as a result a salt (NaCl) and water were formed. Indicators are substances which undergoes a color change in the pH interval of the equivalence point, allowing physical observation of pH change. A procedure for making this kind of determination is called an ACID-BASE TITRATION. Chemistry tutorials. The equivalence point can also be determined visually with an indicator. Titration Lab ?

Suppose the concentration of the NaOH solution was 0.5 M instead of 0.1 M. Would this titration have required more, less, or the same amount of NaOH solution for a complete reaction? Moles Lab Activities Virginia … Several factors can cause errors in titration findings, including misreading volumes, mistaken concentration values or faulty technique. Titrations Questions Answers. LAB DEMONSTRATION ACID BASE TITRATION VIDEO SOCRATIC. Observations. Where there is no base. Question 1 . If we take an overview of the reaction, the protons from the HCl moved to the NaOH or the HCl donated H+ ions to the solution and NaOH gave OH- ions to the solution. 2.
